Description

Technical Field

[0001] The present invention relates to the technical field of conversion sockets, and in particular to a modular converter and a socket having the same. Background Art

[0002] The existing multi-position conversion socket generally includes a shell and a multi-position conversion device, wherein the lower side of the shell is provided with a pin through hole, at least two sides of the upper side, the left side, the right side, the front side and the rear side are provided with a socket panel, each socket panel is provided with a socket group (each socket group consists of two or three sockets), the multi-position conversion device includes a pin assembly and a connection assembly, the pin assembly includes a pin bracket and two or three pins mounted on the upper part of the pin bracket (when there are two pins, the two pins are respectively used to connect the live wire and the neutral wire of the power socket, and when there are three pins, the three pins are respectively used to connect the live wire, the neutral wire and the ground wire of the power socket), and the lower part of the pin extends out of the shell through the pin through hole; the connection assembly includes a connecting piece bracket and two or three connecting pieces, the connecting pieces are installed in the corresponding slots of the connecting piece bracket and are electrically connected to the corresponding pins through conductive members. When in use, the pins of the plug of the electronic product are inserted into the corresponding slots of the connecting piece bracket and contact the corresponding connecting pieces to conduct the circuit.

[0003] However, the existing conversion sockets have the following problems: 1. In order to add multiple USB charging modules, some products have reduced the number of slots, resulting in poor product applicability; 2. Some products have removed the fixing screw holes of the sockets, resulting in a lot of inconvenience in the use of the product (such as inconvenient installation); 3. The internal structure of some products is too complicated and requires the connection of multiple wires, resulting in low assembly efficiency and poor space utilization, which limits the installation of surge protection devices; 4. Some existing live wire connectors and neutral wire connectors are generally installed on both sides of the frame for easy installation and a distance is set between the two (i.e., they do not touch each other), but this also increases the volume of the frame; 5. When the existing converters need to be stacked, it is necessary to change the design of the connector or the structure of the main frame, which has a high production cost. Summary of the invention

[0004] The main purpose of the present invention is to propose a modular converter and a socket having the same, aiming at a modular converter module. Even if a USB charging module is added, the number of slots will not be reduced, and can be increased according to actual needs. At the same time, the modular converter module does not require or can reduce the connection of wires during the installation process, thereby improving assembly efficiency while ensuring the safety of the socket.

[0005] To achieve the above-mentioned objectives, the present invention proposes a modular converter, comprising a main frame, a first connecting plate and a second connecting plate, wherein a first slot and a second slot are provided on at least two sides of the upper side, the left side, the right side, the front side and the rear side of the main frame, the first connecting plate and the second connecting plate are arranged on the same side of the main frame and are staggered with each other, the first connecting plate and the second connecting plate are respectively provided with a first connecting portion and a second connecting portion in opposite directions, and the first connecting portion and the second connecting portion are respectively inserted into the first slot and the second slot.

[0006] A socket comprises a shell, a circuit board arranged in the shell and the above modular converter connected to the circuit board, wherein the circuit board is provided with power pins.

[0007] The technical solution of the present invention makes the modular converter modularized into a whole by installing the first connecting piece and the second connecting piece on one side of the main frame. Setting the first connecting piece and the second connecting piece on the same side can effectively reduce the volume of the main frame, thereby reducing the weight of the modular converter; at the same time, the bottom of the first connecting piece and the bottom part of the second connecting piece extend out of the main frame, and are installed on the circuit board between the extended parts, so that the overall assembly of the socket can be achieved, and the number of modular converters can be increased on the circuit board according to actual needs, thereby increasing the jack group; and during the installation process, the USB charging module can be installed on the circuit board according to actual needs, so that the various components of the socket are modularized, the assembly steps and the difficulty of assembly are reduced, and the assembly efficiency is improved; by setting the main frame to a trapezoidal shape, interference between adjacent plugs during use can be avoided, thereby improving the customer experience of the socket.
